Phase Ib Study of Rocbrutinib in Combination with R-CHOP in Patients with Newly Diagnosed B-cell Non-Hodgkin Lymphoma

Summary

This is an open-label, multicentre Phase Ib study to evaluate the safety and preliminary efficacy of new generation Bruton Tyrosine Kinase inhibitor Rocbrutinib in combination to R-CHOP (Rituximab, Cyclophosphamide, Doxorubicin, Vincristin, Prednison) in adult patients with newly diagnosed, previously untreated B-cell Non-Hodgkin Lymphoma \[Diffuse Large B-cell Lymphoma (DLBCL), Marginal Zone Lymphoma (MZL) or Mantle Cell Lymphoma (MCL)\].

Eligibility

Inclusion Criteria:

* Participants was histopathologically diagnosed with any of the following diseases: DLBCL, MZL or MCL (if enrolled in the dose expansion phase, histological confirmation of non-GCB subtype), and have not previously received anti-tumor systemic therapy or local radiation therapy for the above diseases.
* Participants must have at least one measurable lesion.
* ECOG physical status score 0-2.
* Life expectancy ≥6 months.
* International Prognostic Index (IPI) score ≥ 2 (only participants with DLBCL in dose expansion portion).
* Adequate coagulation, liver, kidney, and hematopoietic functions：PT and APTT \<1.5x ULN; serum bilirubin \<1.5x ULN except in participants with Gilbert's syndrome who must have a serum bilirubin of \<3x ULN, AST and ALT ≤ 3x ULN or \< 5x ULN if hepatic involvement are present; serum creatinine (Scr) ≤1.5 x ULN, or calculated creatinine clearance ≥ 30ml/min by Cockcroft-Gault formula.; ANC≥1500/mm3, hemoglobin≥8.0 g/dL, and platelets \>100,000/mm3 unless deemed related to lymphoma involvement in the bone marrow and felt potentially reversible by the treating physician.
* Women of childbearing potential must have a negative serum or urine (beta-human chorionic gonadotropin \[beta-hCG\]) at screening.
* Women of childbearing potential and men who are sexually active with a woman of childbearing potential must be practicing a highly effective contraceptive measures of during and after the study (90 days after the last dose of ROCBRUTINIB and 12 months after the last dose of Rituximab). Men must agree to not donate sperm during and for up to 90 days after he last dose of ROCBRUTINIB.
* Participants voluntarily enrolled and signed the informed consent form, and followed the trial treatment and visits.

Exclusion Criteria:

* Participants with DLBCL had a history of indolent lymphoma such as FL or CLL (Richter's transformation), or was histopathologically comfirmed with FL (regardless of grade) coexistentially.
* Prior treatment with solid organ transplantation or hematopoietic stem cell transplantation(HSCT) ; expected HSCT during the study.

* Prior treatment with strong/moderate CYP3A4 inhibitors within 5 days or prior foods with inhibitory effects on CYP3A4 within 3 days at screening; requires chronic treatment with moderate/strong CYP3A inhibitors or inducers, or OATP1B1/OATP1B3 sensitive substrates during the study.
* Participants with other malignancies other than the target indications of this study within the past three years.
* Prior treatment with the cumulative dose of doxorubicin ≥150 mg/m2 (or other anthracyclines at doses converted based on cumulative cardiac toxicity)
